This is a vintage set-up. Acoustic Research AR-1W woofer and JansZen Model 1-30 electrostatic transducer. Both tested, fully functional. The cabinets are in good to very good condition. The Model AR-1 was unveiled at the September, 1954, New York Audio Fair. It consisted of a 12-inch woofer designed and built by AR. High frequencies were handled by the 755A, an 8-inch full range driver of Western Electric design, produced by Altec. Both units were in a sealed 3/4-inch thick plywood cabinet filled with fiberglass. The size was just under two cubic feet with dimensions of 25″ x 14″ x 11, noticeably smaller than other high performance loudspeakers. It weighed in at about 50 lbs. A Model AR-1W (a woofer only speaker), shown in Figure 1, was also produced and was intended to be used with a separate high frequency unit such as the Janszen Model 130 electrostatic tweeter. Most impressive was the fact that the Models AR-1 and AR-1W could reproduce frequencies down to 32 cycles per second with very low distortion, something the large mechanical suspension speakers could not do. Among the features of AR woofers built through the late 1960s were a cast aluminum speaker frame, an Alnico magnet, and a treated cloth cone surround for a free suspension. Kloss was put in charge of the AR factory and is credited with 75 percent of the Model AR-1’s production design. Julian Hirsch, who at the time published the Audio League Report, wrote, The AR-1 & AR-1W have established a new industry standard for low distortion bass.
